Description

Technical Field

[0001] This utility model relates to the field of center rest technology, specifically a pneumatic center rest for a precision grinding machine. Background Technology

[0002] A pneumatic center rest for a precision grinding machine is an auxiliary support device installed on a precision grinding machine. It is mainly used to support workpieces with poor rigidity, such as long shafts and slender rods, to maintain the stability of the workpiece during the grinding process and prevent the workpiece from bending and deforming due to cutting forces, its own weight, and other factors, thereby ensuring the machining accuracy and surface quality of the workpiece.

[0003] While existing pneumatic center supports for precision grinding machines can provide some workpiece support, in actual use, the presence of dust and other impurities in the machining environment can lead to their accumulation on critical components such as the clamping wheels. Over time, this dust and impurities accumulate on the clamping wheels, affecting their normal rotation and reducing their supporting effect. It can also cause uneven friction distribution between the clamping wheels and the workpiece, further exacerbating workpiece deformation and ultimately impacting the stability and quality of the entire machining process. Therefore, a new pneumatic center support for precision grinding machines is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a pneumatic center rest for a precision grinding machine, thereby solving the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic center rest for a precision grinding machine, comprising:

[0006] The outer casing has support claws on both the upper and lower sides of the left end face, a support rod at the middle position of the left end face, and a claw head installed on one outer end of the support claw.

[0007] The first air passage is located inside the claw head, and a first clamping wheel is rotatably mounted on one side of the inside of the claw head;

[0008] The second air passage is located inside the support claw, and the output end of the second air passage coincides with the input end of the first air passage. The first air pipe is installed on the outside of the second air passage.

[0009] A hollow frame is installed on the outside of the left end of the support rod, and a second clamping wheel is rotatably installed inside the hollow frame;

[0010] An air guide shell is installed on the upper part of the hollow frame on the left end face of the outer shell, and a second air guide pipe is sealed and fixed at the front end of the air guide shell.

[0011] Preferably, a sealing ring is installed between the support claw and the claw head outside the second air passage, the sealing ring being used to improve sealing performance.

[0012] Preferably, the claw head is provided with a first side frame on both the upper and lower sides near the supporting claw, and the first side frame is integrally formed with the claw head. The first side frame is fixed to the supporting claw by screws, and the screw fixing method makes the first side frame easy and quick to assemble and disassemble.

[0016] Compared with the prior art, the present invention provides a pneumatic center rest for a precision grinding machine, which has the following advantages:

[0017] This invention connects an air source to a first air guide pipe and a second air guide pipe.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides a technical solution: a pneumatic center rest for a precision grinding machine. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 ,include:

[0024] The outer casing 1 has support claws 2 on both the upper and lower sides of the left end face, and a support rod 10 is provided at the middle position of the left end face of the outer casing 1. A claw head 3 is installed on one end of the outer side of the support claw 2.

[0025] The first air passage 4 is opened inside the claw head 3, and the first clamping wheel 5 is rotatably installed on one side of the inside of the claw head 3;

[0026] The second air passage 7 is located inside the support claw 2, and the output end of the second air passage 7 coincides with the input end of the first air passage 4. The first air pipe 9 is installed on the outside of the second air passage 7.

[0027] A hollow frame 11 is installed on the outside of the left end of the support rod 10, and a second clamping wheel 12 is rotatably installed inside the hollow frame 11;

[0028] The air guide shell 13 is installed on the upper part of the hollow frame 11 on the left end face of the outer shell 1, and the front end of the air guide shell 13 is sealed and fixed with the second air guide pipe 14.

[0029] Please see Figure 2 A sealing ring 8 is installed between the support claw 2 and the claw head 3 outside the second air guide 7. The sealing ring 8 is used to improve the sealing performance.

[0030] Please see Figure 1 and Figure 2 The claw head 3 is provided with a first side frame 6 on both the upper and lower sides near the supporting claw 2. The first side frame 6 is integrally formed with the claw head 3. The first side frame 6 is fixed to the supporting claw 2 by screws. The screw fixing method makes the first side frame 6 easy and quick to assemble and disassemble.

[0031] Please see Figure 3 The hollow frame 11 and the support rod 10 are fixed with screws, which makes the hollow frame 11 easy and quick to assemble and disassemble.

[0032] Please see Figure 2 The first air guide 4 is integrally formed with the claw head 3, and the second air guide 7 is integrally formed with the support claw 2.

[0034] This solution involves connecting an air source to the first air guide pipe 9 and the second air guide pipe 14. When the first clamping wheel 5 needs cleaning, the air source outputs air through the first air guide pipe 9, directing the airflow into the second air guide channel 7, and then through the first air guide channel 4 to blow clean the first clamping wheel 5. As the airflow blows clean the exterior of the first clamping wheel 5, the first clamping wheel 5 rotates under the action of the airflow, thereby cleaning the impurities and dust attached to the exterior of the first clamping wheel 5. When the second clamping wheel 12 needs cleaning, the air source outputs air through the second air guide pipe 14 into the air guide housing 13, and the airflow is directed out through the air guide housing 13 to blow clean the second clamping wheel 12. Under the action of the airflow, the second clamping wheel 12 rotates, thereby cleaning the impurities and dust attached to the exterior of the second clamping wheel 12.
